如何为Blackberry推送通知开发服务器端应用程序（面向错误）

Question

我正在使用下面的代码在服务器上为Blackberry推送通知制作通知程序，但在下面显示错误。   任何人都可以帮助我在java中开发用于黑莓推送通知的服务器端应用程序。

    Exception in thread "main" net.rim.pushsdk.commons.PushSDKException: Bad HTTP response      returned: HttpResponse ( net.rim.pushsdk.commons.http.HttpResponse@10a93e5    statusCode = 404    content = https://cp****.pushapi.eval.blackberry.com    contentType = null    headerFields = {null=[HTTP/1.1 404 Not Found], Date=[Tue, 11 Jun 2013 12:38:52 GMT], Content-Length=[0], Server=[Apache-Coyote/1.1]}     )
